| Description: |
| Get measured values from the ADC for these stages. Y is the |
| specific stage number corresponding to datasheet stage names |
| as follows: |
| |
| == ========== |
| 1 LED2 |
| 2 ALED2/LED3 |
| 3 LED1 |
| 4 ALED1/LED4 |
| == ========== |
| |
| Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1 |
| respectively which simply helper channels containing the |
| calculated difference in the value of stage 1 - 2 and 3 - 4. |
| The values are expressed in 24-bit twos complement. |
| The LED current for the stage is controlled via |
| out_currentY_raw. |
